closes #305

m = MagicMock(spec=Instance, name="asd"); m.name -> AttributeError so I have
to set it in an other statement

Unhandled exception: _get_remote_args() got an unexpected
          keyword argument 'activity'

- disk remove with op view in vm detail
- still use old disk remove for removing disks from template
- also fix some resize code

The filtering messed up the host list table for vlans
that contains hosts that are not associated with VMs

Closes #315
